The virtual network interfaces you select depend on how or if you want to connect to the rest of your network. In my opinion the cleanest way is to connect to VMnet8 which connects to your physical network by NAT.
When I expanded the files and opened the .vmx file in VMware workstation it had four network adapters, two on VMnet2, which is a private network seen only by VMs with interfaces on it, and two on VMnet0, which is bridged to the physical network. If you select the bridged network you will need to get the configuration from your network administrator.
I configured my simulator by leaving the first two interfaces on the private network(e0a and e0b) and putting the second two on the NAT network VMnet8 (e0c and e0d)
If you use the bridged network you will need to get IP configuration information from your network admin.
If you select the NAT network you are the network administrator. From your screen shot the NAT subnet is 192.168.0.0. Unless you have changed it the DHCP range is 192.168.0.128 to 192.168.0.254, with a netmask of 255.255.255.0 and default gateway of 192.168.0.2. Your workstation will have an address on that network of 192.168.0.1. You need to select an unused address outside of the DHCP range, you should be safe with anything from 192.168.0.3 to 192.168.0.127, unless you already have a VM using it.
a: hostname: your choice
b. IP address: 192.168.0.10 for e0c (or you can create an interface group with e0c and e0d)
c: netmask: 255.255.255.0
d: gateway: 192.168.0.2
e: timezone: your local time zone
f: password: your choice, it needs to have sufficient complexity or it will be rejected
You are running the Cluster mode simulator. It sounds like what you really want is the 7-mode simulator. Download and install the 7-mode simulator, then it will look like the existing ONTAP 7 or ONTAP 8 filers.
Get the documentation and read at least the Software Setup Guide and the System Administration Guide.
